Amarr Cable & Drum Replacement: The Marietta Owner’s Guide
Amarr cable and drum replacement in Marietta typically runs $130 to $250 for the parts and labor, and our trucks stock the common Amarr-spec cables and drums so most jobs are done same-day. You’ll usually find out this part failed when the door hangs crooked halfway up, or when a frayed cable snaps and the door slams down harder than it should. We quote a flat written price with a written scope before any work starts, per Clause 1 of The Haven Standard, so there’s no surprise on the invoice after the door is back in the track.
Which Amarr Models This Applies To
Amarr builds their residential doors across several series: the Lincoln, Stratford, Heritage, Classica, and Olympus lines are the ones we see most often in Marietta garages. The cable and drum setup varies by door weight and spring type. Lighter single-car doors use a 3-inch or 4-inch cable drum paired with 1/8-inch or 5/32-inch aircraft-grade cable, while heavier double-car Amarr doors often step up to a 4-inch or 5-inch drum and 5/32-inch cable. The drum is the grooved wheel at each end of the torsion tube that the cable wraps around as the door moves.
The reliable way to identify your Amarr part: open the door to waist height, look at the bottom corner bracket where the cable attaches, and read the cable diameter with a caliper, or find the model sticker on the door’s end stile near the bottom panel. If the sticker is gone, the door weight and spring size tell us what drum and cable the door was built with. We match by measurement, not by guess. Servo Garage Doors Marietta is an independent service provider and not affiliated with Amarr, and we carry OEM-spec cables and drums that match Amarr’s factory dimensions exactly. That matters because an undersized aftermarket drum changes how the cable spools, and the door will run crooked or bind within weeks.
Signs Your Amarr Cable & Drum Replacement Is Failing

- Door hangs crooked or jerks on the way up. One cable has stretched or begun to fray, so one side is pulling harder than the other. The drum on that side is usually worn at the cable groove.
- You can see frayed steel strands near the bottom bracket. Cables fail one strand at a time. If you can see loose strands, the cable is past the end of its service life and needs replacement, not tape.
- A loud snap and the door slams down or refuses to move. That’s a broken cable. The door’s full weight is now on one cable or on none, and the remaining side is overloaded.
- The cable is wound unevenly on the drum. A worn drum groove or a stretched cable causes the cable to stack on one side of the drum. The door will bind and eventually stop moving.
- You hear grinding or metal-on-metal noise from above the door. The cable drum may be loose on the torsion tube, or a bearing inside the drum has failed. Left alone, the drum walks inward and eats the cable.

AfterReplacement Cost & What’s Included
Cable replacement on an Amarr door in Marietta runs $130 to $250 installed, and drum replacement falls in the same range per pair. When both cables and both drums are replaced together, which is the standard repair after a full failure, most Amarr jobs land between $200 and $320. The spread comes from door weight: a light single-car Stratford takes lighter parts and less wind-up time than a heavy double-car Classica with insulation.
Every quote includes the parts, the labor, the wind-up and balance check, and a documented photo record of the failed part and the finished repair. Clause 4 of The Haven Standard is why we photograph the failed cable and drum before quoting the replacement. The price is written down and agreed before any work starts. The 365-Day Done Right Promise covers the repair: if it’s not right, we make it right.
DIY or Call Us?

What you can safely do: look at the cable for visible fraying, check whether the door hangs level, and note whether the drum grooves look chewed up. That’s useful information for the phone call. What you should not do: remove or re-wind a cable, loosen a drum set screw, or touch anything on the torsion tube. The torsion spring above the door is under enough tension to cause serious injury, and the cable carries that tension down to the bottom bracket. Releasing it wrong can break bones or worse. If the cable has snapped, the door is no longer balanced, and a partially supported door can drop without warning.
The safe move is a trained technician who carries the right Amarr-spec parts and done this specific repair hundreds of times. Call (470) 486-7771 and we’ll give you a straight price before we touch a bolt.
FAQs
In Marietta’s humidity, Amarr cables typically last 7 to 12 years before they show serious fraying, and drums often outlast the first cable but get replaced with it once the grooves are worn. Garages near the Chattahoochee corridor see faster corrosion on the cable steel because of the moisture in the air. If the door has been out of balance, both parts will wear faster.
Call (470) 486-7771 and we’ll tell you what’s on your door and what it needs. The estimate is free.
No. A frayed cable cannot be safely spliced, and a worn drum groove cannot be machined back to spec on site. The only correct repair is replacement with a matching Amarr-spec part. We don’t patch cables, and we recommend the same to anyone else you might call.
Most Amarr cable and drum replacements take 45 to 90 minutes on site. The bulk of that time is winding and unwinding the torsion spring to transfer tension safely, then balancing the door and running it through several cycles. If the spring is also near failure, we’ll tell you and quote the spring separately before anything gets done.
Yes. Our Marietta trucks carry the common Amarr cable diameters and drum sizes, plus the same for LiftMaster, Chamberlain, Genie, and the other major door brands. Same-day replacement is the norm, not the exception. Call (470) 486-7771 and we’ll confirm the part match before we head out.
